I have put a new double fan Sunon in the laptop however when I try to boot up when gets to the dell screen the fan comes on at high speed and then the computer turns off. If the fans does not go in to high speed made it will boot up.
My qestion is the fan not compatiable or do I have another problem?

I'm not familure with Dell laptops but can tell you this much,

Dell computers use a proprietary case fans.
If they do not spin at a specific speed it cayses an error,

From what you have described I would find out the speed [RPM] of the original fan & get one as close to it as possible without exceeding it.
